ROD-PACKING.

` SPECIFICATION forming part of Letters Patent N0. 730,925, dated June 16, 1903.

Application filed May 19,1902. Serial No.108,088. (No model.)

To all whom it mfnsy concern:

Be it known that I, JOHN S. KLEIN, a citizen oi' the United States, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented new and useful Improvements in Rod-Packing, of which the following is a specification.

This invention relates to rod-packing; and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims.

More particularly the invention applies to rod-packing in which it is desirable to keep the packing medi um or rings cool. Other features of the invention will appear from the specification and claims.

The invention is illustrated in' the accompanying drawings, as follows:

Figure 1 shows a section on the line 1 1 in Fig. 2; Fig. 2, a section on the line 2 2 in Fig.

1. Fig. 3 shows a central section of an alternative construction. Fig. 4c also vshows a central section of an alternative construction.

A marks the cylinder-head; B, the stuffingbox. These maybe of the ordinary construction. Vithin the stuffing-box I preferably place a separate shell C. This shell C may, however, be integral with the walls of the stuffing-box and the stuffing-box may be integral or attached to the cylinder-head. The shell C has the taper bore c,whieh 'rests against the packing-ring c'. -The gland-ring C' is arranged at the outer end of the shell C and is provided with the stud c2, by which. the casing C may be forced into engagement with the packing c.

A ring-casin having tapered outer surfaces is forced into the shell C by means of the gland G. The outer surface of this ring-casing is provided with depressions. As the casing is forced into the shell the edges of the casing form a joint with the shell and form the passages (Z within the shell. The two parts form a joint at CZ". The taper of the shell forces the two parts together, so as to make the joint d* water-tight as well as the contact-surfaces between the shell and the ring-casing. titions or Webs d2 are arranged in the passages d' to strengthen the ring-casin Perforations d are arranged in these webs, so that the Water-jacket of the cylinder.

practically an annular water-passage extends entirely around the ring-casing. Water is admitted through the pipe II and exhausted through the pi pe l-I'. The rings E are placed iu the cavities d and bear against the rod F in the usual manner.

It will be noted that the water-passage d extends on three sides of the ring-cavity (Z and are on surfaces adjacent to the ring-cavity, so that water in the passages absorbs the heat from the rings and cools them. A

In Fig. 3 I show an alternative construction in which the stuffing-box I3 is attached to the cylinder-head A and the shell/G2 is integral with the stuliing-box. The gland G' is threaded directly on the stuffing-box and the waterpassages H2 H are connected directly with The packing-rings E and the ring-casing D are similar to the construction shown in Fig. l.

In Fig. 4 I show another alternative construction in which the stuffing-box B2 is integral with the cylinder A and the shell C is in- Vater is admitted directly from the jacket ofthe cylinder through the passages IlAI II". The packing-ring E and ring-casing D are similar to the construction shown in Fig. 1.

That I claim as new is- 1. In a rod-packing, lthe combination of a packing-ring; a casing having cavities in which the ring is arranged; and a water-passage having surfaces on the casing near the cavity extending on three sides of the cavity.

2. In a rod-packing, the combination of a packing-rin a multiple-part casing in which the ring is arranged; the parts of said casing having water-tight joint; and a water-passage having surfaces on the casing near the cavity, said passage extending by a joint from one part to another.

In a rod-packing, the combination of a shell; a ring-easing fitting in the shell with a water-tight joint and having a water-passage formed between its walls and the wall of the shell.

l. In a .rod-packing, the combination of a shell having a taper bore; and a ring-casing havin taper surfaces to correspond with the bore of the shell, one of said-l.y parts having a depression forming a Water-passage between the shell and the casing.

5. In a rod-packing, the combination of a shell having a taper bore; and a ring-easing having taper surfaces to correspond with the bore of the shell, one of said parts having a depression forming a water-passage between the shell and the casing, said casing having a depression forming a water-passage between the shell and the casing.

(i. In a rod-packing', the combination of a shell; a multiple-part ring-casing arranged within said shell and forming a water-tight between the shell and the casing, and the,

parts of the casing being provided at their outer edges with water-tight joints.

9. In a rod-packing, the combination of a shell having a taper bore; a multiple-part ring-casing having a taper surface to correspond with the bore, the parts forming' w'atertight joints at their edges, and one of said parts being provided with depressions forining water-'passages between the shell and casing all of said joints being closed by the ac tion of the taper as the ring-casing is forced to place.

10. In a rod-packing, the combination of a shell having a taper bore; a ring-easing having taper surfaces to correspond with the shell; and depressions to form a water-passage between the shell and casing, said casing being provided with Webs extending from the bottom of the depression to the shell to strengthen the casing.

1l. In a rod-packing, the combination of a stuffing-box; a detached taper-bore shell; a packing-ring between said shell and stuffingbox.; a ring-casing having a taper surface corresponding with the bore of the shell and p'rovided with depressions forming a water-pasA sage between the shell and the easing-ring.

12. In a rod-packing, the combination of the stuiing-box B; the shell C, having the taper bore; Water-passages II II', leading to and from said shell; the ring-casing D, having the ring-cavities (I, the cavities d', extending on three sides of the cavity d, the Webs d2, and perforations cl3, in the webs, the outei` surfaces of the ring-casing being tapered to fit the shell C, and forming watertight joints therewith, said ring-casing being formed in parts, lthe joint d4, between the parts being closed by the taper eieet of the ring-casing C; and the rings E.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. 4
